#fmt float broken on Ubuntu Precise

[lht]

Assert failed on Ubuntu Precise x86_64. Works fine on another Ubuntu 11.04 (i386).

use std;
fn main() {
  std::io::println(#fmt("%f", 5.82));
  assert(#fmt("%f", 5.82) == "5.82");
}

Is "%f" really defined as "%.2f" in Rust?

I am asking because C, Ruby and Python define "%f" as "%.6f".
Their result of sprintf("%f", 5.82) would be "5.820000" not "5.82".

We should endeavor to do the same thing as glibc's printf. Filed a separate issue for that #1375

This seems have been fixed by 5fd0a3b.
